WHEEL-TIRE.

m i t specification of Letters ramene Patented J an. 1 il 191() Application filed June 4, 1909. Serial No. 500,099.

To all whom it may concern:

Be it known that I, HOWARD I-I. HoDosoN of the 'city of Toronto, in the Province o Ontario,' Canada, have invented certain new and useful Improvements in Wheel-Tires, of

flanges of each section and extending part` projects to form cushions F.

which the following is a specification.

This invention relates to tires of the type in which a rubber tire is formed'in sections having flanged bases held in contact with inwardly turned llanges on a recessed rim b v means of a hoop spring. In such tires I have experienced much trouble owing to wearing of the flan es of the tire sections and to lack of sti ness therein. Further trouble was experienced due to lack of con-l nection between the sections. These troubles I have overcome by providing the base and flanges of eachsection with a metal sheath and by interlocking the sections substantially as hereinafter more specifically described and then definitely claimed.

Figure l is' a longitudinal section of art of a wheel rim showing three sections 0 the tire in side elevation. Fig. 2 is a cross section of the tire and rim. Fig. 3 ls a plan view of the under side of the sections shown in Fig. 1.

A are rubber tire sections each having lateral flanges I formed on its-base.

D are metal sheaths fitted to the base and way up the neck thereof. Rivets E preferably connect opposite sides of each sheath through the neck of the section. These metal sheaths are preferably shorter. than the sections of th-e tire so that adjacent sheaths do not meet andY anelastic cushionis formed between the sections. This feature of importance as otherwise the flexibility of the tire under radial pressure would be interfered with. O enings or slots are formed in the under si e of each metal sheath through which the. rubber of the sections These cushions F engage the hoop spring C which is fitted within the recess formed in the fixed metal rim B which is provided with inwardly turned flanges K which engage-the upper sides of the flanges of the tire sections A. -These cushions F ease the jar of the sectionon the hoop sprn when the wheel is runningon the roa rim flanges and he hoop spring C 1s preferably double as indicated in the draw ing. As it4 is Adesirable that the sections should be so held together as to properly hold them in alinement I preferably provide cach section with a projection G adapted to fit into asimilar-1y shaped recess H formed in the adjacent section which interlocking however does not interfere with the resilliency of the individual section under radial pressure.

It will be found that a tire provided with my improvements will possess great durability Wit i no decrease in elasticity as compared with similar tires unprovided with these improvements.

What I claim as my invention is l. A tire section comprising a rubber section ha ving lateral flanges at each side of its base and a projection at the under side of the base; and a metal sheath embracing the base and lateral flanges of the section and provided with an opening for the projection on the base of the section. 2. A tire section comprising a rubber section having lateral fianges at each side oi its base and a projection at the under side of the base; and a metal sheath embracing the base and lateral flanges of the section slightly" shorter than.the section and provided with an'opening for the projection on the base of the section.

3. In a vehicle/.tire the combination of a fixed recessed rim provided with inwardly extended annular flanges; a rubber tire formed in sections `provided with laterally' extending flanges fitting under thc aforesaid a projection at the under side of the base, the sections being provided with interlocking means comprising a" projection on one-of the two adjacent sections fitting into a recess formed in the adjoining section; a metal sheath embracing he base and lateral flanges of each section and provided with an opening for the projection on the` base of the section; and spring means pressing the sections radially outward.
